Even tho i like and know songs from the Christina Aguilera album, i may admit that it didnt cause much impact, at least in my country. Crazy In Love and Naughty Girl were everywhere
Genie in a Bottle, What a Girl Wants and Come on Over is a 123 punch that so very few artists achieve these days especially for a debut. They are successful and iconic teen pop classic.
The only classic in DIL is probably Crazy in Love.
And I'm saying this in a global perspective. Yonce became a huge worldwide figure in the latter half of her career anyways while X was on a decline.
